ldpc is not configured for fixed rates. This blocks auto rate vs fixed
rate performance comparison. Since firmware is considering ldpc vdev
param for fixed rate selection, it has to be configured to enable ldpc
for fixed rates.

PRI value is used as divider when DFS detector analyzes candidate
radar pulses.
If PRI deviation is big from its origin PRI, DFS detector could miss
valid radar reports since HW often misses detecting radar pulses and
causes long interval value of pulses.
For instance from practical results, if runtime PRI is calculated as
1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
the modular remainder will be 1409 and the delta between the remainder
and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
As a result this radar report will be ignored even though it's valid.
By using spec defined PRI for fixed PRI, we can correct this error.

The number of pulses per burst on Japan chirp radar is
between 1 and 3. The previous value, 20, is representing
number of bursts, but since current DFS detector is using
pulse detection other than bursts, use the pulse number
for correct radar detection.
Also using the highest number helps to avoid false detection.

The remain_on_channel callback needs different
timeout. Calling ieee80211_queue_work() with a
shorter delay after calling it with a longer delay
will not change the timer. This caused the
offchannel timeout worker to not trigger in time
and caused the device to stay on channel longer
then expected. This could cause some problems and
was be easily reproduced with `iw offchannel`
command.

Add support for mesh to ath10k. We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.
Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode. As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true. The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.
When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:
ip link set wlan0 down
iw dev wlan0 set type mp
ip link set wlan0 up
iw dev wlan0 set freq 5745 80 5775
iw dev wlan0 mesh join mesh-vht

The VHT STS CAP shall be reported by firmware to host, like in case of
QCA99x0. For QCA6174 hw family this isn't set for some reason.
So for this particular chips, let's assume it has the ability to
support VHT NDP in up to 4 STSs (which is true by the way).

During long hours of stress testing like AP interface up/down along
with continuous ping flood from a station doing connect/disconnect,
it is observed that the system is not able to allocate DMA consistent
memory of size > 512KB chunks as requested by firmware in WMI_SERVICE_EVENTID.
With the system memory getting fragmented during the run based on the
size of the memory requested, the failure to return physically continguous
memory of high order can happen. Once the system gets to this situation,
bringing up the wifi interface will fail and a system reboot may be needed
to make it work again. This problem is obseved with QCA99X0.
To fix this issue, allocate the DMA memory requested by firmware during
device probe time and keep it during the life time of the device. WMI service
ready event handler is changed to allocate the memory chunks if it is
not already allocated or if the memory allocated for the previous ready
event is not same as the current requested ones. After this patch the
memory usage when wifi is inactive will be inceased by few 100KB to
3MB based on the target type.

MU-MIMO Rx involves different interpretation of
the VHT-SIG-A compared to SU-MIMO.
The incorrect interpretation led ath10k to report
VHT MCS values greater than 9 which subsequently
prompted mac80211 to drop such frames. This
effectively broke Rx with MU-MIMO in many cases
and manifested with a kernel warning in the log
which looked like this:

This adds additional 0x0041 PCI Device ID
definition to ath10k for QCA6164 which is a 1
spatial stream sibling of the QCA6174 (which is 2
spatial stream chip).
The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump

To enable/configure spectral scan parameters in 10.4 firmware, existing
wmi spectral related functions can be reused. Link those functions in
10.4 wmi ops table.
In addition, adjust bin size (only when size is 68 bytes) before reporting
bin samples to user space. The background for this adjustment is that
qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
carries band edge detection data (+32) mainly used in radar detection
purpose. Additional last 4 bytes are stripped to make bin size valid one.
This bin size adjustment will happen only for qca99x0, all other chipsets
will report proper bin sizes (64/128) without extra 4 bytes being added
at the end. The changes are validated in qca99x0 using 10.4 firmware.

Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.
Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.
.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.
Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with
CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.

Vif's vdev_id is used as queue number. However due
to the tx pausing design in ath10k it was possible
for a new interface to be created with its tx
queue stopped (via ieee80211_stop_queues). This
could in turn leave the interface inoperable until
ath10k_mac_tx_unlock() was called.
This problem only affected multi-vif scenarios when
new interfaces were created some time later after
other interfaces have been running for some time
and had Tx queue full at some point prior.
Possible manifestation of the bug was
authentication timeout for a client vif.

The separate load and mask operations are also combined into a single
statement.

This driver is converted to use the common firmware header struct.
Because the old header definition failed to indicate that the multi-byte
entries should be little endian, several problems were thus exposed.
These are fixed.

Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version"
and "fw_subversion") added initialization for fw_version, but failed to
note that the variable in the firmware header is little-endian. The
following Sparse warning results:
CHECK drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types)
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: expected unsigned short [unsigned] [usertype] fw_version
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: got restricted __le16 [usertype] version
When fixing this problem, I noticed that several of the drivers contain
nearly identical copies of the firmware header struct, and that only the one
used in rtl8192c{e,u} had correct endian notation. The struct has been
moved into a common header, and the other drivers will be fixed in
subsequant patches.

There's already a generic implementation so use that instead.

Return type of wait_for_completion_timeout is unsigned long not int.
As time_left is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.
API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/ath9k/link.c:197
int return assigned to unsigned long
Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
Patch is against 4.1-rc3 (localversion-next is -next-20150514)
